ESP32 Forum

I use ESP32-S3 for commercial products and encounter very confusing errors such as: Continuously resetting, unable to start (the error mainly comes from the quartz oscillator block, when removing the module cover and touching the quartz pins, the module starts again), this error often appears when the weather turns cold, the ambient temperature drops to 12-20 degrees Celsius.

Some errors encountered:
- rst:0x3 (RTC_SW_SYS_RST),boot:0xa (SPI_FAST_FLASH_BOOT)
- rst:0x8 (TG1WDT_SYS_RST),boot:0x8 (SPI_FAST_FLASH_BOOT)
- rst:0x7 (TG0WDT_SYS_RST),boot:0x8 (SPI_FAST_FLASH_BOOT)
- USB Unknown Error....

Why would you remove the module cover ?
Touching any products crystal pins will result in the same.

The ESP32-S3 has a temperature range of -40°C to 85°C. I would look elsewhere in your circuit for the problem. All variant's of the ESP32 are known to be a stable product.

When the module had an RST bootloop error, I removed the module and touched the oscillator, the circuit started normally, but when RST, the circuit returned to the above bootloop error.

Not all modules have the above error, when the circuit has an error I leave it for a few months and try again, the circuit starts up normally again.

I use module: ESP32-S3-WROOM-1-MCN4R8
